Contactor feeder
Contactor feeder in M10x is designed for
symmetric 3 phase load or single phase load. All
measurement, control and protection features
which are available to NR-DOL are available to
contactor feeder load.
Unlike the NR-DOL logic in which current feedback
is a built in feature, current feedback is no longer
required for motor status verification in contactor
feeder control.
* The assigned DI and PIN code may change in actual design
